Officials said that 3,300 building owners have not been paying property tax while details of payments by another 12,700 consumers are missing from the system. Officials say that the property tax department of NMMC has been generating bills but these have not been distributed to the owners.

The department is alleged to have sat on issuing bills to these property owners until March 2016. The department, which prided itself on being able to achieve its recovery targets set every year, is now grappling for answers over the administrative and financial discrepancies.

NMMC officials declined to elaborate but has initiated a departmental inquiry against former assessor and collector of property tax, P B Kulkarni. He was placed under suspension in May 2016 and an inquiry was initiated by NMMC commissioner Tukaram Mundhe immediately after taking charge. NMMC officials say the alleged misappropriation of bills occurred during Kulkarni’s tenure.

“The consumers who till date didn’t receive bills are now being provided with a copy that includes existing dues as well as arrears too. The dues are to be paid by March. Simultaneously, an inquiry is underway to look into the discrepancies,” said additional municipal commissioner Ankush Chavan.

Senior officials of the property tax department stumbled upon the anomaly while generating half-yearly bills. “The calculation is simple as per the corporation’s records. There are 3.07 lakh properties registered but when the process of generating half-yearly bills were undertaken, it was found that the system had data of only 2.92 lakh properties,” said an official.

“A rough estimate shows that NMMC lost Rs 900 crore in the last 10 years. We suspect these property owners have been greasing the palms of officials,” the official added. These 3,300 properties were ‘land under construction’ category. Though these properties may have been under construction when the first bills were raised, the properties may have been developed and multi-storied buildings may have come up at these locations, attracting a higher property tax,’’ said officials.

“Ideally for constructing a building, an NOC from the property tax department is necessary. However, if commencement certificates and occupation certificates were issued in absence of an NOC, it only means that the whole scam was carried out with the involvement of officials of various departments. The involvement of some politicians is also being probed,” the official added.

Official under scanner
